Manual means of activating adjustment procedure is achieved by pressing
button. System of
automatic adjustment will carry out the process fully automatically and will inform the user on
successive process stages.
Cycle of automatic adjustment process:
• Balance software detects the necessity of carrying out adjustment and signals it by displaying a
thermometer or clock pictogram and <Cal> sign at the top of the display, about 2-minute long
time interval within which weighing procedure can be completed takes place,
• As the 2-minute long time elapses, balance display indicates message CAL_30
and starts counting down from 30..29..28 to 0 (indicated value is the counter),
• Balance user has 30 seconds to make a decision
• In order to start adjustment, do not take any actions
• In order to complete weighing procedure, press Esc. When pressed, balance returns to
weighing procedure and displays last weighing result. In about 5 minutes balance indicates
CAL_30 message again.
• The adjustment process can be postponed for multiple times, but it needs to be pointed out that
postponing of adjustment for a long time may lead to larger errors of weighing process. The
errors are the effect of temperature changes and as a consequence changes of balance
sensitivity.
Automatic adjustment process has been designed for three different cases:
• Adjustment on plugging the balance to the mains – verified balances.
• Adjustment triggered by temperature change inside the balance. The balance is equipped with
a very precise system for monitoring temperature. At each adjustment process, the temperature
is recorded. The next adjustment is automatically initiated if temperature changes more than
1°C or 2°C (AS, PS series balances) from the last saved temperature.
• Adjustment triggered by elapsing time. You can declare time intervals which are criteria for
balance adjustment (this option is only available for non-verified balances).

• P1.1 INT. CALIB. – Internal adjustment
Start of an internal adjustment process. Adjustment is conducted automatically, and no user
assistance is required. If a weighing pan of the balance is loaded, balance will display
a command ordering to unload the weighing pan. If weighing pan is loaded with a relatively
small mass (up to 10% of balance max capacity) then adjustment process will be carried out
automatically, the load may stay on the pan.
or
• P1.2 EXT. CALIB. – External adjustment (with an external weight)
Adjustment with an external weight, value of which is saved in factory settings (function
unavailable for verified balances).
• P1.3 USER CALIB. – User adjustment (with an external weight)
Adjustment with an external weight of any mass within balance range, however not lower than
30% of Max range (function unavailable for verified balances).
• P1.4 CALIB. TEST – Adjustment test
This fuction enables comparing the result of an internal automatic adjustment with the value of
an internal weight, saved in balance factory parameters. The process is carried out
automatically and its result is shown on the display (if the balance is connected via
communication port with a computer or a printer, the adjustement result will be printed out).
